An egg subscription is the most forgiving income a small flock can earn. You know roughly what you'll make before the hens lay a single egg, you're not standing at a market table all Saturday hoping for walk-ups, and your best customers commit to you for a whole season instead of buying from whoever's closest that week.
Then November comes. The hens molt, the daylight shrinks, and the dozen-a-week you cheerfully promised forty families turns into eight dozen total across the whole flock. Everyone still wants their eggs. You have a third fewer to give.
That winter cliff is the one thing the "start an egg CSA!" posts never mention — and it's the thing that decides whether your subscription quietly makes money or turns into forty apologetic text messages in January. This guide walks the whole model: what an egg share actually is, how to size it to your flock, how to price it off your real cost instead of the grocery shelf, and how to run the pickups and the money without a paper notebook.
An egg share is a promise, not a product
A loose dozen is a product: a customer shows up, you have eggs, they pay, done. A share is a promise. A member pays in advance for a standing quantity — usually a dozen a week — for a set run of weeks, and collects it each pickup day.
That promise is exactly what makes it valuable to you: cash in hand before the season, demand you can predict, and customers who don't drift. It's also the catch. You owe that dozen every single week of the run, including the weeks your hens have other plans. Size the promise wrong and the thing that was supposed to smooth your income becomes the thing you dread.
The number that decides everything: your winter supply
Your flock's summer output is a vanity number. The figure that should size your subscription is what the same birds lay in the dark months.
A flock of 30 hens laying at a healthy summer rate — about 75% of the birds on an average day — gives you roughly 13 dozen a week. Hold that same flock to a 45% winter rate, which is normal without supplemental lighting and gets worse during the autumn molt, and you drop to about 8 dozen a week. Same birds, same coop, 40% fewer eggs.
So here's the rule the posts skip: size your subscription to your winter floor, not your summer peak. If the leanest week of the year is 8 dozen, sell about 8 weekly dozen-shares — not 13. Take the summer surplus to loose sales, where a short week costs you nothing. A share you can always fill is worth far more than one you oversell and then have to short, because the short week is the one your members remember.
(Supplemental light in the coop will lengthen the laying season and is worth considering — but that's a flock decision, not a reason to promise eggs you can't yet see.)
Price the share off your cost, not the grocery shelf
The common mistake is pricing against the store: eggs are $5 a dozen at the market, so you charge $6 and feel clever. The store's cost structure is not yours. Price against your cost, then decide your margin on purpose.
For the same 30-hen flock — figuring real feed and a little for bedding and cartons — a dozen costs about $2.08 to produce, and feed alone is about $1.64 of that. Set a share at, say, $7 a dozen and you're keeping about $4.92 a dozen to cover your time and the coop. Those are example inputs; your feed bill and lay rate are what matter, so run them.
A subscription can usually carry a slightly better price than a loose dozen — the member is buying guaranteed supply and the convenience of not hunting for eggs — or you can offer a small thank-you for paying the whole season up front. Either is defensible. Just make the decision deliberately instead of copying the stand down the road.
Three ways to structure a share that survives winter
There's no single right model — there's the one you'll actually keep. Pick one and say it plainly at sign-up.
- Flat dozen, sized to winter. The simplest. Promise only what you can deliver in your leanest week, and sell every extra egg loose when you're flush. Members never get shorted.
- Seasonal share. Run the subscription only through your strong months — spring through fall — and close it for winter. Members know the season has an end, so the molt is expected, not a broken promise.
- Flex share (a dozen "bank"). A member buys a block of dozens — say 20 over the season — and draws them when they like instead of on a strict weekly cadence. They naturally pull more in summer and fewer in winter, which is exactly how your hens behave.
The failure mode is always the same: a vague "a dozen a week, year-round" that you can't keep once the days get short. Any of the three above beats it.
How a share runs on TallyTill
The reason most small flocks run their eggs on a spreadsheet and a Venmo handle is that the admin — who signed up, who's paid, who's away this week, who still owes — is more work than the eggs. TallyTill's CSA tools are built to carry that part so the subscription scales past what you can hold in your head.
Because the share is prepaid, the pickup itself is just collection. The member grabs their eggs; you (or they) mark the box handed over. No card, no cash, no line.
Sell the surplus at the same stand
In the flush months you'll have eggs beyond the shares — and that's where a self-serve stand earns its keep. Put the loose dozens on the same catalog the subscription runs on. A walk-up customer who wants eggs taps the egg listing on the tablet and pays by tap-to-pay or QR code; a carton with no barcode just needs that tap, or the shopper snaps a photo and the camera matches it to your catalog. Taking cash? That gets recorded too, so your count stays honest.
One catalog covers both the members who pre-paid and the neighbor who pulled in on a whim — and your egg money all lands in one place instead of split across a notebook and three payment apps.
Getting started
Start on TallyTill's free plan, set up your member page, and build one egg share plan sized to your winter floor. Point your regulars to the sign-up link and let the portal handle the roster, the holds, and the balances. Do that, and you'll spend the season filling boxes instead of composing apologies.
Before you set a price or a share count, run your own flock's numbers with the free hens-and-eggs calculator and the egg cost-per-dozen calculator. The hens will tell you how big a promise you can keep.
